Abstract
Fall and spring immigration of Penaeus duorarum to 26 m and 40 m depths was observed during trawl surveys from January 1973 through December 1974 along Florida's northeast continental shelf. Histological examination of ovaries indicated year-round spawning with a primary spawning period during late spring and summer. Larval transport via the Florida Current and Gulf Stream from south Florida to Cape Canaveral and from Cape Canaveral to Cape Hatteras is suggested. Disjunct distribution of adult pink shrimp stocks along the southeastern Atlantic coast of the United States is most likely the result of disjunct occurrence of acceptable sediments (>50% coarse carbonate sands) at suitable depths.
